The invention relates to can-washing machines and more particularly to apparatus for replacing the cover on the can after the cover and can have been washed.

The main object of the invention is to provide a recovering mechanism which may be readily used or applied to can-washing machines of different forms or constructions and which is not dependent for its operation upon the guiding of the covers to a posltlon above the can to render the mechanismeiifective, but which permits the covers being delivered from the washing machine at any convenient point and provides tor carrying the covers from this point to a position over the can after thedelivery-of the can from the machine.

I A further object of the invention is to provide a cover-handling apparatus in which the covers delivered from the washing machine are picked up and carriedby a movable eleetromagnet from said machine to .the then stationary can and deposited thereon auto matically. I

. A further object of the invention is to pro vide a cover-handling apparatus in which the covers'are delivered'one at a time upon a receiving support which is raised in proper timed relation with asw-inging carrier'to bring the cover into magnetically attractive relation with an electromagnet on said can =rier'and is carried therebyto a position over the can, which has been previously discharged from the machine and is deposited in proper position on the can. Y

The invention turther consists in the several features hereinafter setuiorth and-more claims at the con- ,ity conveyor, not shown.

Referring to the drawings, the can-8, which has been washed in .the machine inaninposition on the supporting platform provided by a seriesof rollers'9'mounted-on a frame 10 I Y tromwhich said can is afterward movedv by 80 mechanismhereinafter described onto a grav- The covers 11, which are intermittentlyand progresslvely advanced through the'washing verted position, is delivered by the turning mechan sm, for example such as shown in the above mentioned application, in. an upright machine inan upright position, by an 15.

able feed mechanism, for example suchas shown in the above mentioned application,

are delivered onto a chute or inclined; guide 12 upon which they fall from a vertically disposed position and slide thereon,'bottom side down, onto a movable, horizontal, receiving support 13, which is mounted on the upper end of a vertically reciprocating bar '14 slidably mounted andiguided in the spaced arms of a bracket 15 secured to the machine below the chute 12. I

The support 13 is intermittently raised and lowered by the mechanism more particularly shown in Fig. 3, wherein thenumeral 16 des ignates a'motor-driven shaft, 17 a cam mountto a pivot block 39 which in turn is connected ed on said shaft, 18 a bell crank lever pivotally mounted intermediate its ends at 19 on a bracket 20 secured to the side of the machine, and carrying a roller 21 that is held by the weight of the parts against the cam 17, said lever 18 being'operativelyconnected by a link ,22 with the intermediate portion of a lever 18, link22, lever 23 and links 26 causes the bar 14 and the-cover support 13 to be intermittently raised and lowered, the timing being such that the support 13 is in lowered position. to receive a cover as the cover is" discharged from the washing machine.

, On the slde of the machine opposite to that carrying the support 13 spaced bearing brackets 28 are provided for a vertic'ally disposed oscillatory shaft 29, which has a forked or yoke-shaped fitting 3O pinned to the upper end thereof and forked crank arm 31 secured to the lower end thereof, the fitting 3O pivo ing on the top of the upper bracket 28. The

forked crank arm31 has a pivot block 32 pivotally mounted therein on pins 33, and has theforkedend 34 of a link 35 pivotally connected-at right angles to the pins .33 by pivot pin '36. The other forked end '37 of the link 35 is similarly pivotally connected by pins 38 bya pivot pin 40 to th'eupper forked end 41 of acam-operated lever 42 pivoted a tf43 and a: grooved carrying a roller 44 working in With this cam 45 mounted on the shaft.

7 construction the shaft 29 is oscillated by the cam-45 through its action on the lever 42, link i 35 and crank 31.

Y The yoke-shaped fitting '30 has a plate 46 secured to the arms thereof by screws 47 and this plate has depending spaced arms 48 mounted in slots 49 in the fitting 30 and cooperating with thecyli'n'drical ends 49"thereof to'form supporting bearings for a pivotal trunnion 50 which has a hollow, cylindrical portion 51 infwhich the tubular carrier bar 52 is adjustably secured by bolts 53, said bar being limited in its desired position of vertical inclination by an adjustable stop screw 54 mounted on the transverse portion of the fitting 30 and secured in the desired adjusted position by the lock-nuts 55.

Telescoping within the outer end of the carrier bar 52 is a smaller tubular bar 56 adusta'bly secured thereto by providing a series of spaced holes 57 to receive a. pin 58 passed through one set of these holes and alined holes in the bar 52. r A. forked arm 59 is secured to the" outer end of the bar 56 and has a suitable iron-clad tractiveelectromagnet 60 suspended therefrom by its connection therewith bya pin 61. i

The current supply wires 62 for the electromagnet may pass through the hollow bars 56 and 52 and one of these conductors'may be connected to a direct current generator "63 while the other conductor is connected to the other side of the generator through a suitable circuit closure or switch mechanism 64, whose movable switch arm 65 is under the control ofa plunger'66 held against a control cam 67 on the shaft 16 by a spring 68, the details of' the switch mechanism'itself not constituting part of this invention and hence only shown diagrammatically. The generator is suitably driven from the, main power drive for the machine.

With the above construction the magnet 60 or cover-holding means is moved by the swinging of the carrier-bars 52, 56' and the': shaft 29 to a position over the coversupport 13, by the action of cam 45, lever 42, link35,

crank 31, as the support 13 with the cover 1 thereon is raised from its lower, dotted line position, shown in Fig. 4 to its upper position, at which time the cam 67 has closed the circuit to the electromagnet to energize he same and the cover 11 is then attracted by said'electromagnet and'held thereby while the support 13 starts to move down under the action of the cam 17. As said supportmoves down the carrier arm formed by the parts 29, 52, 56 and 60, withthe cover 11 suspended on the outer end thereof, swings from the position shown in full lines in Fig.2 in the direction of the ar'row'to the 'positionindicated' by the dot and da'shline 69, which brings the cover overand above the conical opening 7 O of the then stationary can 8, which 1 has been discharged from the washing ma-- chine and turned over by'parts ncluding a carrier member 1 of the aforementioned application. With the corer in this position the cam 67' allows the circuit control switch 64 to open'the energlzingicircuit for the; magnet 60- so that thecover' is no longer held thereby anddrops therefrom into the filling opening 7 0' of the can.

The can with the cover in place thereonis then moved off the short, horizontal plat form formed by'the rollers 9 b'y'a pair of kickers or oscillatory arms 72, each of which is mounted on a vertically-disposed pivot shaft 7 3 journalled in bearingbrackets 74 on the frame l0and provided with a crank 75, said cranks being'ccnnected by a link 76for simultaneously swinging both shafts'73 and arms 72 by means of, a crankarm '77 secured to one of said shafts connected by a link 78 to the upperend of a weighted lever 7 9 pivoted at 8 0 and carrying a weight 81' at its other end which holdsits roller 82 against a cam 83 on the rotating shaft 16. This cam I 83 acting through the lever 79, link 78, cranks 77, shafts 73, link. 76'and cranks .75 causes the arms 72 to be intermittently swung in proper timed relation with the mechanism previously described to move the can forwardly after receiving its cover and thus start it on its travel along a suitable gravity conits discharge from the machine is automatically supplied with a cover which, if the operator at the feeding end of the machine is careful, will be the same cover that the can had when it came to the machine.
